Curable composition

Abstract

A curable composition comprising Component (A) a blocked polyisocyanate compound, Component (B) an active hydrogen compound having at least 2 active hydrogen atom-containing groups in the molecule, and Component (C) a catalyst expressed by the following formula (1), (R.sub.1, R.sub.2, R.sub.3, R.sub.4)N.sup.+ Y.sup.- (1) wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 denote hydrocarbon groups of 1 to 18 carbon atoms which are non-reactive to isocyanates and may be the same or different, and said groups may form heterocyclic rings via oxygen or nitrogen atoms, and Y.sup.- denotes an anion of a hydroxide, an alkoxide, an aryloxy or a carbonate, or an anion of a carboxylate, a sulfonate, a phosphate or a borate which may contain hydrocarbon groups. The composition is suitable for chipping-resistant coating material for automobiles.
